v4928.1.5.113 — Opportunity detail deadlock guard

Hotfix for opportunity detail pages failing with 500 Internal Server Error when PostgreSQL raises a transient deadlock while the advanced manual correction card reads reconciliation_items during reconciliation/sync jobs.

• Retries _opportunity_manual_correction_state() once on deadlock/lock-timeout errors.
• Falls back to a safe degraded UI message instead of crashing the opportunity page.
• Keeps the correction card auxiliary; the central opportunity flow continues rendering.
